Geoff Keighley, who’s hosting YouTube Live at E3 2016 on Monday, went on Twitter to tease that they have some big surprises and big names lined up for the 12-hour stream:

Excited by all the amazing friends and developers who will be popping by on Monday’s E3 show. Can’t wait to share more…big surprises.

I genuinely get excited this time of year. Next Monday will be a great day for our industry. World class content is coming. Looking over our show rundown tonight, we have perhaps the best lineup we’ve ever had. 12 hours of amazing news and wall-to-wall games.

The @youtube E3 team is killing it. The best developers. The top YouTubers. United to celebrate the best entertainment medium in the world. It’s going to be such a big day. A marathon. Bringing together generations of gamers and very special guests to celebrate this art form.

Ya’ll aren’t ready for what is about to happen. I’ve been to all 22 E3s. 22!

I promise you our E3 team has worked as hard as ever to bring you the best possible show. The biggest games. The biggest names. The moments. So join us Monday on @youtube I couldn’t ask for a better partner. The scale of what we are doing is massive. Multiple stages. Big names. We will bring pop culture and gaming together in a big way next Monday. That’s the POINT. Let’s GROW gaming together. Tell your friends.

Thank you for trusting me to bring you E3. I don’t take the responsibility lightly. We will work as hard as we can to make this YOUR day.

YouTube Live will also see the world premiere of a new video game-inspired song by Martin Garrix, with Lil Wayne also appearing during the stream.

Earlier this week, Keighley said, “Can’t believe what just got confirmed for Monday @youtube E3 Live.” He also tweeted that June 6 was an “insane day of E3 bookings today. Live show next week will be [hot hot].”
